A sample of an unknown substance has a mass of 0.465 kg. if 3,000.0 j of heat is required to heat the substance from 50.0°c to 100.0°c, what is the specific heat of the substance?
Answers
The specific heat of the substance will be 0.129 J/g°C.
What is specific heat capacity?The amount of heat required to increase a substance's temperature by one degree Celsius is known as specific heat capacity.
Similarly, heat capacity is the relationship between the amount of energy delivered to a substance and the increase in temperature that results.
The given data in the problem is;
Q is the amount of energy necessary to raise the temperature = 3,000.0 j
M is the mass= 0.465 kg.
Δt is the time it takes to raise the temperature.=50°c
s stands for specific heat capacity=?
Mathematically specific heat capacity is given by;
[tex]\rm Q= MC \triangle t \\\\ C = \frac{Q}{M\triangle t} \\\\ C = \frac{3000}{0.465 \triangle 50} \\\\ C =129.0 J/Kg^0C \\\\ C= 0.129 J/g^0C[/tex]

four pieces of graph paper a ruler two pencils a helper Follow these steps: Choose which person will be the sender (satellite) and which will be the receiver (television). Each person then draws a 10" by 10" square on a piece of graph paper. Draw a grid within the square, so that each small square of the grid is about 1 inch square. This should give you an area with 100 squares in it. The size of the small squares will depend somewhat on the graph paper used - make sure you use some of the lines on the graph paper as guidelines. The sender now draws a simple picture within the 10" x 10" square without letting the receiver see what he or she is drawing. The sender should now “read” the picture to the receiver, using a digital code. If a square on the graph paper is blank, the sender says “Zero”; if the square is filled in or has any mark in it at all, the sender says, “One.” Using this code, the sender starts with the top row and reads from left to right, one square at a time. The receiver, upon hearing this code, transfers the information to his own graph paper. The receiver must mark the graph paper by starting with the top row of squares and going from left to right. If the sender says “zero,” no mark is made. If the sender says “one,” the receiver should fill in the square completely! At the end of the first row, the sender should say, “End row 1,” and repeat this at the end of each row. At the end of the last row, compare the two pictures. Check the results to see how accurate the transfer was. Now, get two more pieces of graph paper and draw 10” by 10” squares on them. This time, your grid size should be close to 1/4 inch rather than one inch. You will have many more squares than before! You can use the same drawing or switch people and the new sender can draw another picture. Follow the same procedure. Describe your results. Compare the accuracy of the two pictures drawn by the receiver. Which one is more precise

A torsional oscillator has a period of 0.45 s. If its rotational inertia is 0.25 kg-m2, what is the torsional spring constant of its spring
Answers
The torsional spring constant of the torsional oscillator (I = 0.25 kg · m² and T = 0.45 s) has a magnitude of 48.738 newton-meters.
How to determine the constant of a torsional spring
The torsional spring constant indicates the resistance of the spring to an external moment. The torsional spring constant (κ), in newtons per meter, can be found by means of this formula in function of the period (T), in seconds and the moment of inertia (I), in kilograms per square meter:
[tex]\kappa = \frac{4\cdot \pi^{2}\cdot I}{T^{2}}[/tex] (1)
If we know that I = 0.25 kg · m² and T = 0.45 s, then the torsional spring constant of the spring is:
[tex]\kappa = \frac{4\cdot \pi^{2}\cdot (0.25\,kg\cdot m^{2})}{(0.45\,s)^{2}}[/tex]
κ = 48.739 N · m
The torsional spring constant of the torsional oscillator (I = 0.25 kg · m² and T = 0.45 s) has a magnitude of 48.738 newton-meters. [tex]\blacksquare[/tex]

Answers
1) when we light a matchstick,the energy which got consumed in while rubbing the matchstick against the surface,turns into heat and hence ,it lights , therefore,the energy gets transferred from one type to another which proves the law of conservation of energy.
2) The coal gets burn and generate into electricity which further used by us for various purposes like lighting lamp and since the energy gets transferred from one source to another instead of ceasing, it proves the statement of conservation of energy.
3) As the pendulum swings in air , it continues to move from one point to another, changing potential energy to kinetic energy due to the motion that's taking place and unless an external force interferes, it's speed won't increase as at some point due to the friction by air will resist the movement resulting in decresement of kinetic energy and increased potential energy, thus ,at some point it will come to rest .
4) No ,it doesn't , because due to the force of friction,the disturbance in the movement of it ,takes place, making it stop at a specific point after some time.
5) As the pendulum swings in air , it continues to move from one point to another, changing potential energy to kinetic energy due to the motion that's taking place and unless an external force interferes, it's speed won't increase as at some point due to the friction by air will resist the movement resulting in decresement of kinetic energy and increased potential energy, thus ,at some point it will eventually come to rest .

It's a frightening idea, but what would be the sound intensity level of 100 physics professors talking simultaneously
Answers
The sound intensity level of 100 physics professors talking simultaneously is equal to 72 decibel.
Given the following data:
Sound intensity = 52 dB.What is sound intensity?Sound intensity can be defined as a measure of the power of a sound wave per unit area. Thus, sound intensity is a quantity that can be used to measure the energy of sound and its unit of measurement is Watts per square meter.
How to calculate the sound intensity level.Mathematically, sound intensity level is given by this formula:
[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]
Note: The reference value of sound intensity is equal to [tex]1.0 \times 10^{-12}\;W/m^2[/tex]
Thus, the sound intensity for one (1) professor is given by:
[tex]I_1 = 1.0 \times 10^{-12} \times 10^{5.2}\\\\I_1=1.585 \times 10^{-7}\;W/m^2[/tex]
For 100 professors, the sound intensity is:
[tex]I_{100} = 1.585 \times 10^{-7} \times 100\\\\I_{100}=1.585 \times 10^{-5}\;W/m^2[/tex]
Substituting the parameters into the formula, we have;
[tex]\beta = 10 log(\frac{1.585 \times 10^{-5}}{1.0 \times 10^{-12}})\\\\\beta = 10 log(15.58 \times 10^{6})\\\\\beta = 10 \times 7.2\\\\\beta =72\;dB[/tex]

Complete Question:
One physics professor talking produces a sound intensity level of 52 dB. It's a frightening idea, but what would be the sound intensity level of 100 physics professors talking simultaneously?
Answer:
72dB
Explanation:
The sound intensity level of one prof is given, that's your β1 (which is equal to 52dB).
Using the sound intensity level formula:
β1= 10log ([tex]\frac{I}{I_{o} }[/tex]) = 52 dB
*This will be useful later on [even if β1 is known]
Set up the formula for β2 (β2 is going to be the new sound intensity, the one for the 100 profs):
β2 = 10 log( [tex]\frac{ 100 I}{I_{o} }[/tex] )
*You need to multiply the intensity of one professor by 100 (because now there's more)
*do some algebra- pull out the 100
β2 = 10 log (100 [tex]\frac{I}{I_{o} }[/tex])
*use log laws
β2 = 10 ( log(100) + log ([tex]\frac{I}{I_{o} }[/tex]) )
*Now, isn't there a familiar part? Well, yes! The expression for β1!
β2 = 10log(100) + β1
β2 = 10log(100) + 52dB
*use your calculator
β2 = 73dB
^^^ that's your new sound intensity level

Answers
The value of resistance that should be used is 244.74 Ohms and the resistor must be connected in parallel.
Given the following data:
Initial resistance, R₁ = 150 Ohms.Final resistance, R₂ = 93 Ohms.What is a parallel circuit?A parallel circuit can be defined as an electrical circuit with the same potential difference (voltage) across its terminals.
In order to determine the magnitude of a resistor that should be added to this branch of the circuit, the electrical circuit would be connected as a parallel circuit.
Next, the total effective resistance of this electrical circuit is given by:
RT = (R₁ × R₂)/(R₁ - R₂)
RT = (150 × 93)/(150 - 93)
RT = 13950/57

Positive Outcomes are -

We face a more serious gamble of experiencing serious wellbeing impacts, including respiratory sicknesses, neurological issues, decreased fruitfulness, harm to our insusceptible framework, and expanded dangers of getting malignant growth.
The outside contamination is related with hearth assaults. Open air contamination causes lung issues like asthma assaults or bronchitis .
